1 o aZZ whom it may concern Be it known that I, JOHN ANDREW BELT, a citizen of the Dominion of Canada, residing at Toronto, Province of Ontario, Dominion of Canada, having invented a new and useful Centrifugal Liquid-Evacuator for the Creation of a Vacuum Within Itself IVhen in Operation in Liquids, do hereby declare that the following is a full, clear, and exact description of the same.

My invention relates to the construction of a machine which when rapidly operated by power supplied to the driving shaft will compel the evacuation of the area within its sectional and movable sides of any liquid that may have entered therein, so long as the operation is continued.

I attain this object by the mechanism illustrated in the accompanying drawings, in which Figure 1 represents the frame (when con structed in oblong form). Figs. 2 and 3 represent the covers of same. Fig. 4 the side cover or casing; Fig. 5 the driving shaft with wheels attached; Fig. 6, the pin-hinged carriers to which the side sections are attached and carried by them; Fig. 7, represents two sections of the side. Fig. 8 presents a view of the machine complete, eX- cept part of the casing which is absent to give a partial interior view. Fig. 9 makes a similar exhibit of the machine in cylinder or drum form.

In Fig. l, the frame comprises two similar collars or sections 2 2, which are held firmly directly opposite each other by holding bars 3 3 attached to both, at the required distance. At each end of both framecollars are bearings 4 4: for the driving shafts; and around each collar outside and within the holding bars are protecting ledges 5 which will minimize the return pressure at the ends of the side sections of liquid that has been forced out of the openings between the said side sections.

Fig. 2 exhibits the cover of one of the frame collars; it fits down over it as far as the holding bars and is soldered or otherwise fastened so that their connection is air-tight; it has rims with extensions 11 11 which enable it to meet the side casing all around; it has bearings for the driving shafts 4t 4; and an opening 12 through which liquid may enter through a pipe connection by gravitation or be drawn by suction produced by the operation of the machine.

Fig. 3 shows the cover for the other frame collar; it is also fastened on to-same airtight, and has a rim with extensions 11 11 to meet the side casing all around; and has bearings 41- 4 for the driving shafts.

Fig. 4. shows the side casing, which is constructed so as to meet the collar covers around the exterior of the machine and is soldered or fastened to them at its edges in an air-tight manner; it has recesses to contain the holding bars, 10 10; and has an outlet 13 through which liquid from within will be forced out by the centrifugal action of the machine, and may be forced through a pipe attached to said outlet. 7

Fig. 5 shows a driving shaft 6 with wheels attached 7 7. The wheels extend to the line between the ledges (5 5) of the frame collars, and have recesses in their rims to receive the pin-hinges of the carriers (Fig. 6) one driving shaft is carried through one of the frame collar covers and has gearing 14 at its end to which power is supplied by connection with a shaft run by hand, engine, or motor; and the motion thus produced will draw the pin-hinged carriers with the movable side sections around the frame collars; the other driving shaft and wheels being moved by this motion.

Fig. 6 represents a carrier, to which are attached by bolts the movable side sections; the carriers are shaped so that when pinhinged together they will hold the side sec tions in the position that one edge of each is a space to the inward of the nearest edge of the next section adjoining; they fit over the rims of the wheels between the recesses which receive the pinhinges; they are thus enabled to move and carry the side sections around with the wheels and along the straight sides of the frame between.

Fig. 7 shows two of the side sections 9 9, attached to carriers as above set forth.

In Fig. 8 is exhibited a view of the machine with all parts in place, a section being removed from the casing &c to give a partial interior view; 4, bearings for driving shafts; 6, the driving shafts; 7, wheels; 9 side sections; 10 recesses in casing to contain the holding bars; 11 cover rim extensions; 12, iii-let pipe opening in cover; 13, outlet pipe opening in side casing; 14 cog for connection with driving power.

Fig. 9, exhibits the machine in drum or cylinder form. One driving shaft 6 only is necessary; and. in smaller sizes only one wheel 7 is required; also there is only one bearing 4 4 in each collar 2 2 and collar cover. 5, the protecting ledges; 9 the side sections; 10 recesses holding frame holding bars; 11 cover rim extensions; 12 inlet pipe connection; 18 outlet pipe connection; 1&

cog for connection of driving shaft with power supply.

The machine is operated so that the edge of the side sections inclined inward. will precede the rest of same; when it will perform the work, that is have the utility of, a centrifugal pump in transferring liquids.

What I do claim as my invention and desire to secure by Letters Patent is 7 1. In a device of the class described, the

v combination of a frame composed of two similar sections, holding bars securing said sections together, a shaft journaled in each section, a sectional side inclosing the space between the sections and adapted to be moved thereabout by the shaft, an inclosing casing for the frame having an inlet opening communicating with the space between the sections and an outlet opening, and means for rotating the shaft.

2. In a device as defined in claim 1, the sectional side inclosing the space between the sections composed of slats hinged together with the edge of one slat offset with respect to the adjacent edge of the next succeeding slat.

3. In a device as defined in claim 1, wheels secured to said shaft and adapted to engage the sectional side for moving the same.
